RADARCONFIG

Configure the Emulated Radar Output

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, SPAN CPT7, SMART7, SMART2

Firmware Stream:     

Use this command to configure the Emulated Radar (ER) output.

The ER signal is output on the VARF or EVENT_OUT1 pin of the receiver.

1

Rate at which the output frequency is adjusted

(default = 10HZ)1The number of samples used for smoothing depends on both the update_rate and resp_mode parameters. For instance, if the update_rate is 5 Hz and the resp_mode is 2000 ms, the number of samples used will be 10.

The threshold is only applicable when the response mode is set to 2.

Mode

Description

1

Immediate. This results in the lowest latency at the cost of higher noise

2

Automatically switch between 1000 and 500 depending on speed. When speed is below the Threshold parameter, use Response Mode 500. Otherwise, use Response Mode 1000.

500

Signal is minimally smoothed resulting in low latency but increased noise.

1000

Output signal is smoothed over a smaller window resulting in less latency than 2000 and less noise than 500.

2000

Output signal is smoothed to reduce noise at the cost of higher latency
